Researchers turn the public’s ideas into reality

By Ioanna Lykiardopoulou

A robot fish that collects microplastics from waterways has been turned from an idea into a working prototype. The design was brought to life after it won the University of Surrey’s public competition, the Natural Robotics Contest.

The contest, which ran in the summer of 2022, invited the public to submit an idea for a bio-inspired robot that could help the world.

An international panel of judges chose the robot fish concept designed by student Eleanor Mackintosh because it could help reduce the amount of plastic pollution in water. The winning design was subsequently turned into a functioning prototype.

The robotics panelists and researchers, led by Dr. Robert Siddall, turned Mackintosh’s design into a 3D-printed prototype about the size of a salmon.

Named “Gillbert,” the device consists of a flooded head unit and a watertight tail unit. Thanks to a set of gills on its sides and a fine mesh in between them that can sieve about two-millimeter particles, the robotic fish filters the water and keeps the microplastics inside its container as it swims.

Gillbert has already been tested in the lab and local lakes — and it even glows in the dark.

Interestingly, Gillbert’s design is open-source and free to download from the contest’s website. This means that anyone with a 3D printer can create their own microplastic-sucking fish.

But the best part about the robot is that it highlights how public engagement and academic resources have the potential to tap into Europe’s brightest minds and bring innovative ideas into life.

The next Nature Robotics Contest will be announced in spring 2023. That means if you have a brilliant idea to help save the planet, you’ve got some time to outline it and be in with a chance of making it reality.
